Cheap drinks!!

So, in Vegas, you can pay for a drink, or, not pay for a drink. Many strip resorts have bars which have a gaming machine built into the top of the bar, whether it be video poker or whatever else. If you walk up the bar and order a drink or beer, it will probably be $3 to $10. That same drink will often be free if you're playing a casino game. So... if you need a drink, just sit down at one of the gaming machines at the bar, who even cares what it is, plug a dollar in and immediately order whatever drink you want. If you "slow play" the machine, you could walk away spending as little as 25 cents, plus a dollar or two tip (don't forget to tip, don't be 'that guy'), rather than spending several dollars and walking away pissed off. It's a win-win.
